I have a problem to configure my new D3 840 and specially to Y axe. This machine save two motor and two relay on this axe.
But actually the UC CNC software managed only one (Y2 end relay).
Cabling and installation are correctly done (when a change Y1 and Y2, my problem is always on Y1 port).
Can you please me ?
Thank you in advanced for your help

On the UCCNC, Y2 must be configured as a slave axis of Y (not just another output).I have a problem to configure my new D3 840 and specially to Y axe. This machine save two motor and two relay on this axe.
But actually the UC CNC block blast software managed only one (Y2 end relay).

Go to Axis setup → Slave axis, assign Y2 to Y, and enable the second home switch in I/O setup.
If Y1 still doesn’t respond, check port/pin assignment in I/O — the issue is likely configuration, not wiring.
